Comparison of Infrared, Radio waves, Microwaves

 

	Infrared	Radio Waves	Microwaves
1	Infrared is used for short-range communication like TV remotes, mobile phones, personal computers, etc. In science, the Infrared is part of a spectrum that is not visible to the human eye	Radio waves are the  type of wireless communication that can travel large distances as well as can penetrate any wall	Microwaves are a line of sight transmission, meaning both the antennas sending and receiving should be properly aligned.
2	The frequency range of infrared rays 300GHz – 400THz	The frequency range of radio    waves:3KHz – 1GHz.	Microwaves have a frequency Range between 1GHz – 300GHz.
3	The limitation of infrared rays is that they cannot penetrate any obstacles and can only use for short-range. Also, Infrared is used in night vision cameras as it has thermal properties. The frequency range of infrared rays 300GHz – 400THz	It can travel large distances as well as can penetrate any wall ( Omni-directional,	They are unidirectional, as they can move in only one direction, and therefore it is used in point-to-point communication or unicast communication such as radar and satellite.
4	Infrared is one of the secure wireless communication mediums as it is used for short-range. Also, unlike other wireless mediums, infrared is quite inexpensive, and this is some reason it is used in many electronic devices.	Radio waves can travel to long distances so it is used for long distance communication and there is no need of digging and spreading wires.	Advantages of microwaves then we say that it is a very fast way of communication, that can carry 25000 voice channels at the same time. Also, it is a wireless communication medium so there is no need of digging and spreading wires.
5	Infrared waves are used in TV remotes, mobile phones, personal computers	Radio waves are used in AM and FM radios, and cordless phones.	Microwaves are used in mobile phones communication and television distribution.
